iphone - memory leak using MBProgressHUD -

-

i using mbprogresshub, variations on code found here.

some things code:

  • the code in app delegate
  • a number of other classes call it
  • i'm using asynchronous nsurlconnection
  • i not declare it: @property (nonatomic, retain) mbprogresshud *hud;
  • i not: @synthesize hud;
  • (and of course not release in dealloc)

i use follows:

- (void)setsearchingmode:(bool)issearching {     // when network action, toggle network indicator , activity indicator     if (issearching) {         [uiapplication sharedapplication].networkactivityindicatorvisible = yes;          uiwindow *thewindow = [uiapplication sharedapplication].keywindow;         hud = [[mbprogresshud alloc] initwithwindow:thewindow];         [thewindow addsubview:hud];          //hud.labeltext = @"connecting";         [hud show:yes];     } else {         [uiapplication sharedapplication].networkactivityindicatorvisible = no;          [hud hide:yes];         [hud removefromsuperview];         [hud release];     } }  - (void)setsearchingtext:(nsstring *)whattosay {     hud.labeltext = whattosay; }

i sure code causing memory management problem somewhere. in crash log, get:

exception type: exc_bad_access (sigbus)
exception codes: kern_protection_failure @ 0x0000000c

0 libobjc.a.dylib 0x000027d8 objc_msgsend + 16
1 0x00003120 -[myappdelegate setsearchingmode:] (myappdelegate.m:363)
2 0x00003458 -[myappdelegate connectiondidfinishloading:] (myappdelegate.m:341)
3 foundation 0x00032896 -[nsurlconnection(nsurlconnectionreallyinternal) senddidfinishloading] + 62
4 foundation 0x00032818 _nsurlconnectiondidfinishloading + 72

in connectiondidfinishloading call:

[self setsearchingmode:no];

i tried making property accessors hud, not able around line "[mbprogresshud alloc] initwithwindow" - , don't want keep on alloc'ing ivar!

thanks, if can point me in better direction here..

if happen end sequence of:

[self setsearchingmode:yes]; [self setsearchingmode:no]; [self setsearchingmode:no];

that code crash described because of dangling reference hud. when [hud release];, add hud = nil; after line.

it isn't memory leak; over-release. or, more likely, dangling reference.

(and of course not release in dealloc)

why not? if retain it, better release it!

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

-
i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
